Formula
Loan = Price × (1 − Down%) P&I = Loan × i × (1+i)^n ÷ ((1+i)^n − 1) Monthly total = P&I + Tax/12 + Insurance/12 + HOAWorked example
A 400,000 home with 20% down leaves a 320,000 loan. At 6.5% over 30 years, principal and interest is about 2,022.62 per month; adding 400 tax, 125 insurance gives roughly 2,547.62.
Frequently asked questions
What down payment avoids mortgage insurance?
Many conventional lenders require private mortgage insurance below 20% down. Rules vary by country and lender.
Should I pick 15 or 30 years?
A 15-year loan has a higher payment but far less total interest; a 30-year loan keeps cash flow flexible.
Are taxes and insurance fixed?
No. Both usually rise over time, so treat the totals as today's estimate.
